All features are designed to be atomic, independently testable, and fully integrated with existing code. - -**Key Design Principle**: All conversions MUST preserve hash integrity for book matching. When converting EPUB→KEPUB, store BOTH hashes in `media_item_formats` table to ensure cross-device matching still works. - ---- - -## Table of Contents - -1.

[Testing & Documentation](#testing--documentation) - ---- - -## Phase 1: File Conversion Pipeline - -### Overview - -Implement on-the-fly EPUB→KEPUB conversion with **dual hash storage** to ensure book matching continues to work after format conversion. This is CRITICAL for the cross-device sync system. - -### Key Requirements - -1. **Dual Hash Storage**: Store both original EPUB hash AND converted KEPUB hash in `media_item_formats` table -2. **On-Demand Conversion**: Convert EPUB→KEPUB when requested via OPDS with `?format=kepub` -3. **Hash Preservation**: After conversion, both hashes are queryable for book matching -4. **Conversion Caching**: Store converted files to avoid re-conversion -5. **Format Integrity**: Ensure converted KEPUB maintains all reading progress markers - -### Architecture - -``` -User requests book via OPDS with ?format=kepub - ↓ -Check media_item_formats table for existing KEPUB - ↓ -If KEPUB exists and is recent (< 24 hours): - → Serve pre-converted file - → Set X-Bookmann-KEPUB-SHA256 header - ↓ -If KEPUB doesn't exist or is stale: - → Convert EPUB→KEPUB on-the-fly - → Calculate SHA-256 of converted KEPUB - → Store in media_item_formats (with converted_from_format_id) - → Serve converted file - → Set X-Bookmann-KEPUB-SHA256 header - ↓ -Device downloads book with hash in response header - ↓ -Device syncs progress using hash for matching -``` - -### Database Schema - -**Existing Table** (already in schema.sql): -```sql --- No changes needed -

SHA-256 is only for matching books across devices, preventing format conversion issues. - -2. **Collections ≠ Device Inventory** - Collections are organizational metadata (like "smart playlists"). Books can be in collections without being on any device. Progress/annotations sync independently of collection membership. - -3. **OPDS for Acquisition, Internal APIs for State** - Two layers serve complementary purposes: - - OPDS: "What books are available to download?" (public catalog) - - Internal APIs: "How do I manage my books/sync state?" (private management) - -4. **Dual Hash Storage Preserves Integrity** - Store both original EPUB hash (`epub_sha256`) and converted KEPUB hash (`kepub_sha256`) in `media_item_formats` table. OPDS responses include format-specific hash in headers, enabling sidecar matching even after conversion. - -5. **Three-Tier Authentication** - Separate systems for different purposes: - - Tier 1 (Web/Mobile): JWT tokens for user authentication and permissions - - Tier 2 (Sync APIs): Device tokens for progress/annotation sync - - Tier 3 (OPDS): Device tokens for catalog access (optional per-device) - -6. **Terminology Separation** - Always use "Collections" terminology in Bookmann UI. Map Collections to device-specific "Shelves" only at API/device level. Kobo devices see "Shelves", KOReader/Web/Mobile see "Collections". Prevents legal issues. - -7. **OPDS Primary for All Devices** - Kobo, KOReader, Web, and Mobile all use OPDS as primary book delivery method. Sidecar files provide fallback/enhanced features but are optional. - -8. **System Configuration Flexibility** - Use `system_config` table to store base URLs (`base_url`, `opds_base_url`, `api_base_url`). Sidecar generation reads from these values, enabling flexible deployment (different domains, reverse proxies) with user overrides available. - ---- - -## Database Schema - -### Schema Overview - -**7 new tables** + extensions to 4 existing tables - -### Table: media_items (Extended) - -```sql --- Universal identifiers for cross-device matching -ALTER TABLE media_items ADD COLUMN file_sha256 CHAR(64);

Always used for progress tracking, never SHA-256. SHA-256 is only for matching books across devices. -- **ContentId**: Device-generated identifier (e.g., Kobo's "kobo_abc"). Mapped to Bookmann UUID in `device_catalogs` table. Used for progress sync after OPDS downloads. -- **SHA-256**: Cryptographic hash of file contents. Used for content-based matching across devices. Critical for identifying same book on different devices. -- **OPF UUID**: Unique identifier from EPUB metadata ``. High-confidence identifier format. -- **OPF Identifier**: Any identifier from EPUB OPF file (custom format). Medium-confidence identifier format. -- **ISBN**: International Standard Book Number (13 digits). Medium-confidence standard identifier. -- **ASIN**: Amazon Standard Identification Number (10 characters). Medium-confidence standard identifier. -- **Collections**: Device-neutral organizational groups in Bookmann (e.g., "Science Fiction", "Reading"). Books can be in collections without being on any device. Collections organize library, not track device inventory. -- **Shelves**: Device-specific organization (e.g., Kobo's terminology). Map Collections to device-specific "Shelves" only at device-level. Bookmann UI always uses "Collections" terminology. -- **OPDS**: Open Publication Distribution System. Industry standard for book catalogs. All e-reader platforms have OPDS clients. Kobo, KOReader, Aldiko, FBReader, Web browsers can use OPDS catalogs. -- **Internal APIs**: Bookmann's private REST/WebSocket endpoints for state management. Web and mobile apps use these directly. Used for two-way sync, collections, WebSocket real-time updates. -- **Device File Alias**: Mapping of device-specific file paths to Bookmann UUIDs. Enables cross-device matching when same book has different file paths. -- **Hash Confidence**: Scoring system (0.0-1.0) for automatic book matching reliability. Higher values = more reliable match. -- **Dual Hash Storage**: Storing both original EPUB hash (`epub_sha256`) and converted KEPUB hash (`kepub_sha256`). Preserves hash integrity when files are converted. OPDS responses include format-specific hash for sidecar matching. -- **Format Conversion**: Transcoding between book formats (EPUB → KEPUB). KEPUB adds Kobo-specific markup. Critical for Kobo optimization but shouldn't break progress tracking. -- **Media Item Formats**: Tracks all format versions with their hashes. Pre-convert EPUB to KEPUB during scan for optimal performance. -- **System Config**: Key-value store for system-wide settings (base_url, opds_base_url, api_base_url). Enables flexible deployment. -- **OPDS Tokens**: Per-device access tokens for OPDS catalog browsing. Optional - can also support user-scoped and admin tokens. -- **Sidecar File**: `.bookmann.json` - Unified configuration file for devices. Contains OPDS URLs, sync API endpoints, book mappings, collection mappings. -- **Auto-Assign Rules**: Configurable criteria for automatically adding books to collections. Fields: genre, series, author, language, publisher, copyright_year, tags. Operators: equals, contains, starts_with, ends_with, greater_than, less_than. -- **Sync Direction**: For device shelf mappings. 'bidirectional' (sync both ways), 'book_to_device' (send to device), 'device_to_book' (read from device), 'none' (no sync). -- **View Settings**: Per-device preferences for how collections are displayed (grid vs list, which collections are visible). -- **Unlinked Book**: Progress record without proper media_item_id or failed ContentId lookup. Needs manual user resolution. - ---- - -## Summary - -This comprehensive implementation plan provides: - -- **7 new database tables** with proper indexing -- **50+ API endpoints** across 6 layers (identification, collections, OPDS, sync, configuration) -- **10-week phased implementation** with clear deliverables -- **Complete device setup guides** for Kobo, KOReader, Web, and Mobile -- **Three-tier authentication model** for security (JWT, device tokens, OPDS optional) -- **Glossary** of all terminology and concepts -- **Testing strategies** covering unit, integration, and manual validation - -The plan is designed for systematic execution while maintaining architectural consistency and enabling human oversight throughout the development process. All decisions from our conversations have been incorporated, providing a complete roadmap for implementing Bookmann as a comprehensive cross-device ebook management system. \ No newline at end of file diff --git a/PHASE6_SUMMARY.md b/PHASE6_SUMMARY.md deleted file mode 100644 index 5b107d1..0000000 --- a/PHASE6_SUMMARY.md +++ /dev/null @@ -1,220 +0,0 @@ -# Phase 6 Implementation Summary - -**Status**: ✅ **COMPLETE** -**Date**: 2026-02-01 -**Phase**: 6 (WebSocket Real-time Updates) from COMPLETION_PLAN.md - ---- - -## Overview - -Phase 6 (WebSocket Real-time Updates) from the COMPLETION_PLAN.md has been **verified as fully implemented and functional**.
